BioBizz Bio pH+ — Organic pH Increaser for Nutrient Control
Best for: Organic growers who want to manage pH without harming soil microbes
Our thoughts
If you're running organic nutrients and your tap water's pH is drifting high, or you're using RO and need to dial it back up, this does it properly. The key thing: it's humic acid-based, so it won't trash your living soil. That's the real win here.
BioBizz Bio pH+ is a 100% organic pH increaser formulated from natural humic acids. It's designed to raise the pH of your nutrient solution without the harsh chemicals that kill off the beneficial microbes in your growing medium. Whether you're running soil, coco, or hydro, this gives you precise pH control while keeping everything organic.
How it compares
This sits in the organic pH regulation category, designed specifically for growers who won't compromise on microbe safety.
- 100% organic formulation — no synthetic acids or harsh chemicals
- Preserves beneficial bacteria and fungi in living soil systems
- Works across all growing mediums: soil, coco, hydro, aeroponics
- Weaker than synthetic pH+ options, but that's intentional — safer incremental dosing
- Pairs perfectly with BioBizz Bio·Down for complete pH management
If you're using synthetic pH adjusters and wondering why your soil's gone dead, this is the alternative that actually makes sense.
Usage guidance
Basic application
Apply 0.1ml of Bio pH+ to increase pH by roughly 0.1 points. Mix well and retest. Small steps, every time — don't try to fix it in one hit. Wait 10 seconds after mixing before rechecking.
When to use it
BioBizz nutrients naturally settle to the optimal range of 6.2–6.3 on their own. Bio pH+ is mainly needed when your tap water pH is too high, or if you're running RO water and need to bring it back up before feeding. Once the mix is right, leave it.
Testing and adjustment
Mix your nutrient solution first, let it circulate, then test pH with a calibrated meter. If it needs raising, add Bio pH+ in small increments. Stir for 10 seconds between each adjustment. Once you hit 6.2–6.3, you're done.
Storage
Keep the bottle sealed and away from direct sunlight in a cool, dry place. This is an organic product with strict pH values, so good storage keeps it stable.

Our take
This is a proper organic pH management tool, not a compromise. The humic acid base means you're adjusting pH without nuking the living side of your medium — which is where half your nutrient cycling actually happens. If you care about soil biology, this makes sense.
Worth picking up if you're serious about organic growing and want reliable pH control without the guilt. Good time to buy while stock lasts.
